Stood up to drill (4)
I believe the answer is:
bore
This might be a double definition.
'stood up' is the first definition.
'bore' can be an answer for 'stood' (I've seen this in another clue). I'm not certain of the 'up' bit.
'drill' is the second definition.
(I know that drill can be written as bore)
'to' acts as a link.
Can you help me to learn more?
(Other definitions for bore that I've seen before include "No fun" , "Pierce or tire with tedium" , "... endured" , "Person who talks tediously" , "Drill a hole in" .)
